This class will teach you how to analyze data with Large Language Models (LLMs). LLMs such as ChatGPT are powerful. To maximize your productivity---and stay relevant---you should aim to delegate as much of your workflow to these language engines as possible. This means you should switch from analyzing data with a spreadsheet to analyzing data with a computer language---such as R---which LLMs excel at reading and writing. This class will prompt you to make the switch. You will use ChatGPT to create R programs that manipulate and analyze large operational datasets. You will perform in-depth analyses of Alibaba's deliveries, the Italian judiciary's case scheduling, a Chinese supermarket's supply chain, the auto industry's supplier network, Wine Spectator's reviews, and safety breaches at nuclear power plants. You will use an R textbook the instructor wrote specifically for this class (no previous R experience is assumed). Finally, 100% of the class will be "open ChatGPT."
